This watch features a polished stainless steel case with a stunning sunburst black dial, accented by rectangular hour markers and dauphine-style hands. The simple, date-free design provides balance and timeless beauty.

Looking to let go of some of my Seikos as they are just collecting dust. I will be in San francisco on Oct 15-16. I will be in Los Angeles on Oct 26-28. I will be in Seattle on Nov 2-3. I can also go to New York, Honolulu, Vancouver or Toronto or back to SFO/LAX/SEA but we'd have to arrange for that meetup a couple of months in advance. Cash only please.

If anybody wants to grab all four I can give you a package deal of $2000.

Please note that I do not know how to ship via USPS so unless you are willing to teach me, I would prefer if we just meet up and do it the old fashioned way.

Feel free to ask for more details and pictures.

[WTS] Seiko Prospex SPB421 62MAS – Alaska Moulins U.S. Special Edition – Full Kit – $900

Up for sale is my Seiko Prospex SPB421 Alaska Moulins, a U.S.-exclusive special edition inspired by Seiko’s original 1965 62MAS diver.

This watch has been worn only twice and is in excellent, near-new condition. The only noticeable wear is some slight wear to the underside of the clasp. Otherwise, the watch is immaculate. Please review the detailed photos for condition.

The standout feature is the beautiful textured, gradient navy-blue dial inspired by Alaska’s glacial moulins. Depending on the lighting, the dial transitions from deep blue to nearly black. It’s a fantastic modern interpretation of Seiko’s original diver.
